Accentra YAL-AU4604LN-626 – Frequently Asked Questions

1) Will the Accentra 4604LN entrance lever fit a 1-3/8 inch door, or is it only for 1-3/4?
Both. The 4604LN adjusts from 1-3/8 inch through 1-3/4 inch door thickness, so the same lock covers older interior doors and standard commercial 1-3/4 inch openings. The front is universal for flat and beveled door edges too, so you don't need to specify the bevel when ordering. Standard backset is 2-3/4 inches, with 2-3/8 available to order, which matters if you're working off an existing bore.
2) Do I have to specify handing for the Accentra 4604LN lever lock?
No handing to specify. The 4604LN is non-handed and the strike is reversible, so one lock covers left and right hand openings. That is why it works well for a property manager buying a batch for mixed doors, you order by finish only, not by door swing.
3) Will the Accentra 4604LN latch into the strike already in my frame?
The 4604LN uses a 1/2 inch stainless steel latchbolt throw, which is the standard cylindrical latch projection, so it will engage a normal ANSI cylindrical strike prep. The strike supplied is a 1-1/4 inch curved lip sized for a 1-3/4 inch door. If your frame is set back further from the door face and needs a longer lip, other lip lengths are a special order item, so measure from the stop to the door face before you order.
4) What does entrance function mean on the Accentra 4604LN, and is it the right function for an office door?
Entrance function on the 4604LN means the outside lever locks and unlocks, and the key retracts the latch from outside. It's a single cylinder lock, so the inside lever is always free for egress. That fits a tenant suite door, an office, or an apartment entry where staff control the lock from inside. If you want a door that stays locked outside at all times and can only be keyed open, a storeroom function is the right call instead, like the Cal-Royal AG05 Grade 2 storeroom leverset. For a room that must lock and unlock from outside by key only while the inside stays free, look at classroom function such as the Cal-Royal AG03.
5) Can the Accentra 4604LN go on a labeled fire door?
Yes. The 4604LN is UL-cUL fire rated up to 3 hours, so it's usable on labeled openings up to that rating, and it carries ANSI/BHMA A156.2 Series 4000 Grade 2 certification. It's also listed as Windstorm certified under 4600LN, though wind-borne debris openings are governed by your local code, so verify the assembly listing for that use.
6) Can I get the Accentra 4604LN with an interchangeable core so it works with my existing SFIC keying?
Yes. The 4604LN accepts 6 and 7 pin SFIC. The standard build ships with a brass 6-pin conventional cylinder, keyed random, with two keys. Note the conventional cylinder is 6-pin only, 7-pin conventional is not offered, so if your facility keys 7-pin you need to go the SFIC route.
7) What is the closest Grade 2 commercial entrance lever lock to the Accentra 4604LN?
The Hager 2525 is the nearest straight equivalent. Both are Grade 2 cylindrical entrance-function lever locks: the 4604LN is a Grade 2 entrance cylindrical lever with the Augusta lever, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle. Door thickness overlaps as well - the 4604LN adjusts from 1-3/8 inch to 1-3/4 inch, while the 2525 covers 1-3/8 inch to 2 inch, so the Hager reaches thicker doors. The Cal-Royal AG00 entrance lever is another keyed entrance option, supplied with a 6-pin Schlage C keyway and a 2-3/8 inch backset, against the 4604LN standard 2-3/4 inch backset.
8) The door is 2 inches thick - what entrance lever works where the Accentra 4604LN does not fit?
The 4604LN adjusts from 1-3/8 inch to 1-3/4 inch, so a 2 inch door is past its range. The Hager 2525 Grade 2 commercial cylindrical entry lock covers 1-3/8 inch to 2 inch. The Deltana 6201 Manchester, 6411 Morant, and 6431 Linstead entry levers each cover 1-3/8 inch to 2 inch as well. If the opening also calls for Grade 1, the Dexter C1000 asylum function covers 1-3/8 inch to 2 inch, and the Falcon K101 passage runs 1-3/8 inch to 2-1/4 inch.
9) Is there a Grade 1 lever lock to use instead of the Accentra 4604LN on a high-traffic opening?
Yes. The 4604LN is certified ANSI/BHMA A156.2 Series 4000 Grade 2. For a heavier duty cycle on a keyed opening, the Dexter C1000 Entry/Office is Grade 1 with a clutching keyed lever and covers 1-3/8 inch to 1-3/4 inch doors, the same thickness range the 4604LN handles. The Corbin Russwin CL33903 electrified fail-safe lever is Grade 1 and fits 1-3/4 inch to 2 inch doors. On non-keyed openings in the same run, the Falcon T101 and Falcon K101 are both Grade 1 heavy-duty passage levers.
10) What should I use instead of the Accentra 4604LN if the door needs to stay locked from outside at all times?
The 4604LN is an entrance function lock, where the outside lever is unlocked or locked by the occupant. If the requirement is a lever that is always locked outside and always free to exit, that is storeroom function: the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Hager 2580 is a Grade 2 storeroom lock with the Withnell lever. For a classroom opening keyed outside only, the Cal-Royal AG03 classroom lever is Grade 2 with a 6-pin Schlage C keyway and a 2-3/4 inch backset, matching the 4604LN standard 2-3/4 inch backset.
11) Which lever locks look like an alternative to the Accentra 4604LN but will not actually secure the door?
Several levers in the same visual family carry no latch or no lock. The BEST 9K 1DT and BEST 7KC 1DT are single dummy trim - a lever on a rose with no latch at all. The Baldwin Estate 5103 comes as a left hand half dummy and a right hand half dummy, and the Emtek Arts and Crafts and Cortina dummy pairs are likewise dummy function. The Corbin Russwin 585F715 is a lock lever for the ED8000 pushpad exit device, that is, trim rather than a complete cylindrical lockset. The 4604LN is a keyed single cylinder entrance lock with a 1/2 inch stainless steel latchbolt and a guardbolt that deadlocks the latch when the door closes.
12) The building keys on Schlage C - which entrance lever alternatives to the Accentra 4604LN come in that keyway?
The 4604LN ships with a brass 6-pin keyed-random cylinder and two keys, with 6 and 7 pin SFIC available. If the facility standard is Schlage C, the Cal-Royal AG00 entrance lever is a Grade 2 keyed entrance lever supplied 6-pin Schlage C keyway KD with a 2-3/8 inch backset, for doors 1-3/8 inch to 1-3/4 inch. The Cal-Royal AG03 classroom lever is also 6-pin Schlage C KD, on a 2-3/4 inch backset. The Arrow MK33-BD-CS asylum lock is a Grade 2 conventional cylinder in Schlage C keyway if the opening is an institutional or utility door.
13) Which fire-rated lever locks compare to the Accentra 4604LN on a rated opening?
The 4604LN is UL-cUL fire rated up to 3 hours and windstorm certified as the 4600LN. Among the peers that carry a fire rating, the Corbin Russwin CL3110 is a Grade 1 fire-rated passage/closet lever for 1-3/4 inch to 2 inch doors, the Falcon K101 is a Grade 1 fire-rated passage lever for 1-3/8 inch to 2-1/4 inch doors, and the Arrow MK02-TA is a fire-rated privacy lock with a Tudor knob. Those three are non-keyed functions, so on a rated opening that must key, the 4604LN entrance function is the one that locks.
14) Is a Grade 2 cylindrical lever like the Accentra 4604LN enough for a high traffic commercial door, or do I need Grade 1?
Grade 2 covers normal commercial duty, offices, tenant entries, retail back-of-house, and multi-family corridors. Where the door gets abused or sees very heavy cycling, a main entry, a school corridor, a hospital wing, step up to Grade 1. Options we carry in Grade 1 cylindrical include the Dexter C1000 Series entry/office lever, which fits 1-3/8 to 1-3/4 inch doors like the 4604LN, and the Corbin Russwin CL3100 Series, which is vandal resistant and fire rated but wants a 1-3/4 to 2 inch door.
15) I need a matching lever on doors that don't need to lock. What pairs with the Accentra 4604LN?
The 4604LN is the keyed entrance function in the Accentra 4600 Series with the Augusta lever, so passage and privacy versions in the same series and lever design are what keep the trim consistent down a corridor. If you're mixing brands on the non-keyed doors, Grade 2 passage levers we stock include the Falcon B101 and the Hager 2510 Withnell, and the Hager 2540 privacy lever covers bath and bedroom doors, all rated for 1-3/8 to 2 inch doors on the Hager side.
16) What is the guardbolt on the Accentra 4604LN and why does it matter for security?
The guardbolt is the small auxiliary plunger beside the latch. When the door closes it rides the strike and deadlocks the 1/2 inch latchbolt so it can't be shimmed or carded from outside. It's standard on all locking functions in this line, including the entrance function, which is what makes it acceptable on a tenant or office entry rather than just an interior door.
17) How does the Accentra 4604LN arrive keyed, and can I key it into my master system?
Standard build is keyed random with two brass 6-pin cylinders' worth of keys furnished, meaning each lock arrives on its own random key rather than matched to your system. To bring it into an existing facility keyway or master system, order the SFIC version, 6 or 7 pin, and drop in your own cores. Conventional cylinders here are 6-pin only.
18) Which lever locks match the Accentra 4604LN but for the non-keyed doors on the same job?
The 4604LN is keyed, single cylinder, entrance function. For the closet, corridor, and bath doors on the same floor, the Grade 2 non-keyed counterparts include the Falcon B101 cylindrical passage lever, the Hager 2510 passage lever with the Withnell design, the Design Hardware J75 passage lever, and the Arrow GL01 passage lever with the Sierra lever. For privacy openings, the Hager 2540 Withnell lever and the Arrow MK02-TA Tudor knob privacy lock cover bed and bath. Dummy trim to match a run comes from the BEST 7KC single dummy trim, Grade 2 medium duty.
19) What replaces the Accentra 4604LN if I want keypad entry instead of a key?
The 4604LN is a keyed lock with a brass 6-pin keyed-random cylinder and two keys furnished. To drop the key entirely, the Delaney LP250 is a Grade 2 electronic keypad leverlock, the Emtek Classic keypad leverset is a keypad option in the Classic series, and the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function, ADA compliant, for doors 1-3/16 inch to 2 inch. The Lockey 1150 mechanical keypad lever set has an adjustable backset and covers 1-1/8 inch to 2 inch doors, a wider range than the 4604LN 1-3/8 inch to 1-3/4 inch.
20) I need an electrified version of the Accentra 4604LN for an access control tie-in - what is the equivalent?
The 4604LN is a mechanical keyed cylindrical lever lock and has no electrified option in its own series. For a card reader or access control tie-in on a cylindrical prep, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock at 12VAC/DC for 1-3/4 inch to 2 inch doors. Note the door thickness difference - the 4604LN adjusts from 1-3/8 inch to 1-3/4 inch, so on a 1-3/8 inch door the Corbin electrified lever is out of range and the mechanical lock is the fit.
21) What is the difference between the Accentra 4604LN and a keyed entrance knob lock like the Arrow HK11?
Trim type is the difference that decides ADA compliance and how the door is operated. The 4604LN is a lever, in the Augusta lever design. The Arrow HK11 is a keyed entrance cylindrical lock with a ball knob, on a turn-pushbutton function, Grade 2, for doors 1-3/8 inch to 1-3/4 inch - the same door thickness range the 4604LN adjusts across. Both are keyed entrance cylindrical locks; only the 4604LN uses a lever.
22) Is there a vandal resistant alternative to the Accentra 4604LN for an abused opening?
The 4604LN is built on a heavy-gauge steel, die-cast, zinc-plated and chromated mechanism at Grade 2. Where the opening takes abuse and the door is 1-3/4 inch to 2 inch, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock, fire rated, in passage/closet function - so it suits an opening that does not need to lock. For a keyed abused opening, the Dexter C1000 Classroom Security lever is Grade 1 with a clutching lever for doors 1-3/8 inch to 1-3/4 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum function lock.
23) What finishes does the Accentra 4604LN Augusta lever come in?
Six finishes: 605 bright brass, 606 satin brass, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, and BSP black suede powder coat. For matching a building already standardized on commercial hardware, 626 satin chrome is the common spec finish. The BSP black is the one to pick if you're matching newer black trim packages.
24) What's inside the Accentra 4604LN, and will it hold up in a school or healthcare corridor?
The chassis is heavy-gauge steel, die-cast, zinc-plated and chromated, which is the corrosion treatment you want on interior commercial doors that get cleaned frequently. Combined with Grade 2 certification and the 3 hour fire rating, it's specified for offices, schools, healthcare, retail, warehouse and multi-tenant residential. For a lever that gets hung on hard, a clutching Grade 1 chassis such as the Dexter C1000 classroom or the Falcon T101 with pressure release is the heavier-duty route.
25) What is a residential-style entrance lever alternative to the Accentra 4604LN for apartment interiors?
The 4604LN is a commercial Grade 2 lock. On unit interiors where a commercial grade is not required, the Kwikset 200BRNL Breton passage lever is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the Kwikset 300BRNL Breton privacy lever is Grade 3 across the same thickness range - a matched passage and privacy pair. The Bravura Miramar, Atlanta, Orlando, and Tampa passage leversets are Grade 2 with round trim, except the Tampa, which uses square trim. All of those are non-keyed, so the entrance door itself still calls for a keyed lock like the 4604LN.
